We tested the XAV2001 using the same methodology we use for wireless routers, and it offered about the same speed as the average speed of a wireless-N router at a distance of 100 feet. The adapter registered a speed of around 22.9Mbps, just slightly faster than the 22.6Mbps of the Plaster Network PLN3. At this speed, the XAV2001 adapter can finish transmitting 500MB of data in slightly less than 3 minutes.
This speed, though not as high as we hoped, will provide enough bandwidth for most Internet-related activities, such as surfing, playing online games, or even streaming Web videos.
When it comes it stream high-def content, especially from another network computer, though, we found that the adapter can only handle a single stream at a time. And even then, when a movie that's very large was used, the player would have to stop to rebuffer once in a while, especially when we jumped from one part of the movie to another.
Note that the adapter's performance depends on the electrical wiring and will vary depending on the location.
Overall, the XAV2001 adapter's performance met our expectations. It's a decent and reliable replacement for a wireless signal and is definitely better than having to run network cable to that far corner of the house.
